" The Cessna 421C Golden Eagle is a pressurized "cabin class" aircraft that offers comfort, speed, reliability and predictable
handling in an airplane that can climb to a ceiling of 30,000 ft and a cruise speed of up to 258 knots.

At time of release, no other aircraft could fly further, faster, higher and carry as much
load in any comparable piston twin class. The Golden Eagle's performance equals
many turboprops, yet costs hundreds of thousands less to own and operate. Highly
competitive and built for the business aviation market.
